Popeye (chess)

From Wikipedia, the free encyclopedia

Jump to: navigation, search

Popeye is a freely available chess problem solving software that specializes in fairy chess and heterodox genres.

Popeye has no graphical interface by itself but it can be used in DOS, Windows, Linux, Mac OS and many other OS since it comes with source code in C which can be compiled. Popeye is one of the most complete solving programs: it knows about direct mates, helpmates and selfmates but also problems with fairy pieces and different fairy conditions. It knows how to combine most of these variants, e.g., it can solve Circe helpmates with grasshopers. It can list tries and set play, which makes it invaluable for checking composed problems.

The original author of Popeye was Philippe Schnoebelen, who wrote it in Pascal under MS-DOS around 1983-84. From the beginning, the aim was to solve and especially check chess problems before they were published in magazines. The original Pascal code was later donated to new developers, in the spirit of the free software movement, so that it could be converted to C, further developed, and maintained. The main contributors were Elmar Bartel, Norbert Geissler, Thomas Maeder, Torsten Linss, Stefan Hoening, Stefan Brunzen, Harald Denker, Thomas Bark and Stephen Emmerson.
